ROTATING POLISHER.

SPECIFICATION forming part of Letters Patent N 0. 614,873, dated November 29, 1898. A li ti n filed March 5, 1896. Renewed June 30, 1898. Serial No. 684,799. (No model.)

To all whom it may concern.-

Be it known that I, JOHN A. KURTZ, a citizen of the United States, residing at Aliegheny, in the county of Allegheny and State of Pennsylvania, have invented or discovered new and useful Improvements in Rotating Polishers, of which the following is a specification.

Inthe accompanying drawings,which make part of this specification, Figure 1 is a vertical section of my polisher; Fig. 2, a horizontal section of the same; Fig. 3, an elevation of the case; Fig. 4, a top view of case when a crank is employed to rotate the brush; Fig. 5, a vertical section of Fig.4; Fig. 6, a Vertical section of a polisher where the brush has merely a head instead of being inclosed in a cup; and Fig. 7, a plan of the bottom of the polisher, which acts as a button-holder.

My device is particularly adapted to the polishing of buttons, and more especially when they are in position on the garment; but it is by no means confined to this article and may also be used to polish articles which are detached and supported or held in contact with the brush in any suitable way.

The usual way of polishing buttons which are already sewed upon garmentssuch, for instance, as military or other official unifor1nsis to take two strips of wood, hinged together at one end and corresponding in length to the edge of the garment bearing the buttons. The two pieces of this clamp are swung together, pinching between them the thread of the series of buttons, leaving the buttons standing above the surface of the clamp. The line of buttons is then rubbed with a brush bearing polishing powder or paste, while the cloth between the buttons is protected by the clamping strips of wood. My device may be used with such a clamp, but does not require it, as I have shown far simpler and more compact means for holding the button.

I will describe the construction and use of my polisher when applied to buttons on a coat or other garment, and its application to other purposes will then be readily understood.

2 is a metal case, preferably stamped out of thin sheet-brass, which I call the upper cup.

3 is a cup, preferably formed in the same manner and from the same material. 4 is a second like cup, but desirably larger, which I call the lower cup. These cups are placed back to back and secured together by rivets a a or in any other proper manner.

5 is a spindle secured in the upper part of the case 2 and on which cups 3 and 4 revolve freely and to which is attached a spring 6, coiled around the spindle and in the cup 3.

Around the cup 3 and between the same and the case 2 is coiled a tape, cord, or spring 7, attached to cup 3 and with its end extending through slot 8 in the side of the case and intended to act in opposition to spring 6.

In the lower cup 4 is secured a brush 9, either of wool, bristles, 850., having a suitable head 10. The lower surface of the brush projects slightly down from the cup 4.

11 is a bottom cap closing the polisher and having a radial slot 12, which is designed to hold the shank of the button 13.

It is apparent if the tape 7 is pulled out the brush will be rotated in one direction, coiling up spring 6, which in turn as soon as the tension on the tape is released will rotate the brush in the opposite direction. These motions will readily and rapidly polish the button. The same effect may be accomplished by substituting a crank 14, as seen in Figs. 4 and 5, to secure a rotary motion. In Fig. 6 I show the sides of the cup below the brushhead 10 omitted. This construction permits the edge of the brush to spread out into contact with the inside surface of the case 2, and thus makes more friction. The construction is inferior in this respect to that shown in Fig. 1, when a wool or like expansion brush is used, although with a bristle-brush there would be very little difference.

Having described my invention, I claim 1. In polishing devices the combination of a case; two cups set in said case back to back and secured together; a brush secured to one cup and means for rotating both cups contained in the other cup.

2. In polishing devices the combination of a case; two cups set in said case back to back and secured together; a brush secured to the lower cup; means for rotating the cups and a bottom cap for the case, designed to hold the article to be polished.

3. In polishing devices, the combination of a case; two cups set in said case back to back and secured together; a spindle secured to the cups and journaled in the top of the case;

1'0 a winding-tape attached to said spindle and coiled Within theupper cup; a spring acting against said tape coiled around the periphery of said upper cup and attached thereto and a brush secured to the lower cup.

In testimony whereof I have hereunto set I5 my hand this 4th day of March, A. D. 1896.
